firefox-60.5.0-2.el7.centos.x86_64 and Netflix

Hi all,

Since the last upgrade to firefox-60.5.0-2.el7.centos.x86_64 on my
CentOS 7, it is no longer possible to watch Netflix with my Firefox, it
always says that "Firefox is installing components needed to play the
audio or video on this page. Please try again later."
But nothing happens and Netflix is no longer readable with Firefox...
I tried downgrading to firefox-60.4.0-1.el7.centos.x86_64 and al is now
correct with Netflix...
Anyone had experienced the same behavior ?

CentOS 7, rsyslog and redis

Is there a sensible way to get rsyslog to talk to redis on CentOS 7.
The official way is to use the omhiredis plugin, but that doesn't seem
to exist in the CentOS 7 repositories? (It's how I do it on my Fedora

The long version:

I'm trying to rationalise logging and am using an ELK stack.

C7, enable an abrt for a daemon

I've mentioned here before that gssproxy is crashing all over the place

I enable the daemon to give me an abrt with information? I'm just not sure
of what the right word is for systemd, so online searching isn't always

Thanks in advance.

CentOS 6 and 389 Directory Server

I'm not sure it this is the correct location to ask these questions, but ...

In the past when I worked for a living the place where I worked had
thousands of RHEL Linux servers on various hardware, but the access was
controlled by Windows Active Directory and a third party piece of
software that was the middle-man between the 2.

Now that I no longer work I'm trying to build a CentOS Linux environment
where the access is controlled by 389-Directory Server.


Hi All - I have a systemd service file to start my application.

Part of my service file is:
ExecStart=/path to start
ExecStop=/path to stop

This works fine "normally".

However - when I do a "yum update; and reboot" my script detects a kernel
change and now does a number of "recompiling" steps for drivers and such
before starting my application.

persistent generic device for tape changer

An UDEV rule could help? I have not found any example.

CentOS 7.6 update with gettimeofday()

In my app compiled on another linux I am getting
Assertion 'clock_gettime(clock_id, &ts) == 0' failed at
src/shared/time-util.c:34, function now(). Aborting.
when calling gettimeofday() on an update CentOS (did not fail in 7.5).
Is it possible that the update has changed the size of the types in the
timeval struct and causing the crash? Or has there be some for of bug
fix etc?

Back to c7 and firewalld

If I've missed someone's response, apologies.

As I said, my converted rules seem fine, and I can run the script that
issues a bunch of direct rules for the built-in FORWARD rule...

C7 and firewalld, ongoing

I've got my direct rules, converted from a C6 iptables-save. I load them -
they're to add to the built-in FORWARD chain. They all seem to load... but
then, when I try to --reload, I get
Error: BUILTIN_CHAIN: chain 'FORWARD' is built-in chain

CentOS 7 - AltArch i386 - DVD iso?

C7, firewalld and rich rules

Hi, again, folks,

I'm trying to convert a number of iptables rules to firewalld rich
rules. I need to do this, because this is, in fact, a firewall, to
protect access to servers with sensitive data. It will limit access to
the servers behind it to a specific network, and nobody else, and allow
only certain services through.

What I've been trying to find is a script/program that converts the
output of iptables-save to something I can feed to firewall-cmd.
Anyone have a link to such?

I admit this is annoying.

Applying changes to route-eth0

I have a series of static routes in route-eth0

Recently I had to made changes and could not find an effective way to
get the old routes out and the new routes in.

ifdown-route seems to apply the content of route-eth0 to take down the
routes listed and ifup-route brings up routes based on route-

So what ends up is that the old routes never go away, just new routes added.

ifdown eth0; ifup eth0

works, but is a bit heavy-handed for only changing routes.

So how do I clear out the routing table and have it rebuilt based on
ifcfg-eth0 and route-eth0 without bouncing the interface completely

SELinux policy vs. static web content


Some time ago I wrote an introductory article about SELinux on my blog.
I'm currently updating it for my new blog, and I found a curious change
in SELinux policy. Here goes.

For demonstration purposes, I'm using some static webpages, more exactly
the default pages found in /usr/share/httpd/noindex, which I simply
copied over to /var/www/html.

As a first practical example, I'm copying this stuff over to /tmp/backup
and then move it back again.

Requirement already satisfied (use --upgrade to upgrade):

You are using pip version 8.1.2, however version 19.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

How do I get it to go ahead

Signature Pad (Evolis Signotec Sig100)


Please forgive me for being off topic and really off list !!!

I am trying to get a Sig100 signature pad to work with Centos 7.6 machine and am not
getting much support from the manufacturer. The product is sold as linux compatible, but
so far it is not. I have been able to download their software on a microsoft system and
see that the unit does work on microsoft.

My question to everyone on the list is have any of you had any brand of signature pad work
with Centos 7.6? If so I would surely appreciate knowing the brand and how you did it.

C7, mdadm issues

I've no idea what happened, but the box I was working on last week has a
*second* bad drive. Actually, I'm starting to wonder about that
particulare hot-swap bay.

Anyway, mdadm --detail shows /dev/sdb1 remove. I've added /dev/sdi1... but
see both /dev/sdh1 and /dev/sdi1 as spare, and have yet to find a reliable
way to make either one active.

Actually, I would have expected the linux RAID to replace a failed one
with a spare....

CentOS will support openssl 1.1.1 in future version of CentOS

PXEBoot/Diskless client NFS issue

Hey CentOS list!

I've got an oddity with a diskless client setup that I suspect is the
result of the initrd.img I'm using, or some parameter I'm unaware -- or I
need to build my own initrd image (and could use some assistance on what
has to be done in that department)

Testbed is defined as:

ip: with dhcp server, tftp server, nfs server

Early on in the boot cycle, it grabs a DHCP address of,

C 7 and gssproxy

Ok, folks,

I brought this up some time ago, and got no replies. We have a good
number of systems - > 100 - and we use sssd. On the C 7 boxen, which is
most of them, gssproxy *frequently* (like once a day or so) dies with a
SEGV. It restarts fine. Dies again eventually.

ARE other people seeing this? If so, I guess we get to file a bug
report with upstream. Speaking as an old C programmer, dying with a
SEGV? Really? In production?

fixable issue.

C7, and my RAID

Ok, I think my only choice at this point is to delete and recreate the

I see that I can do an mdadm --remove /dev/md0, then, the page I see that

I do find it interesting that scan works, but explicitly assembling
apparently remembers the drive that died, and wouldn't even look at it.
